Hows The Fishing

Walleyes:  The famous Turtle Flambeau Flowage, (19,000 acres of water) is rated by theWisconsin D.N.R. as having one of the best walleye populations per acre of water in the state. Laid out with open mud flat areas, miles and miles of river channels, log jamms, rock, and sand shorelines, submerged as well as visible stump fields, hundreds of center lake rock and mudd humps, back bays, islands, bogs, and numerous weed beds makes for excellent fish habitat.


Smallmouth Bass:  Although much known for its fantastic walleye fishing the Turtle Flambeau Flowage also boasts a excellent population of Small Mouth Bass. With 19,000 acres of superb smallmouth habitat, abundant feed, and acres of prime spawning areas the small mouth population on the Turtle Flambeau Flowage has exploded in the last six years. Commonly referred to as “footballs”, the Turtle Flambeau Flowage produces much heavier smallie than the average inch to pound ratio than most other bodies of water. From early spring to late fall the small mouth can be found roaming the various structures of the TFF.


Musky:  In order to determine the status of the musky population, survey crews returned after the walleye spawning season to obtain information on the general health of the musky population. A total of 253 musky were captured through this effort. Of the total fish sampled, 14% or 36 fish were larger than 40 inches in length. 30% (76) were greater than 36 inches. The largest musky sampled was 51+ inches in length and over 45 lbs. Based on this survey, the Flowage continues to demonstrate its ability to provide outstanding trophy musky angling opportunities.
